The Caterpillar C9.3B Engine is designed for electronic controls. The integral on board computer controls the operation of the engine. Current operating conditions are monitored. The Electronic Control Module (ECM) controls the response of the engine to these conditions and to the demands of the operator. These conditions and operator demands determine the precise control of fuel injection by the ECM. The electronic engine control system provides the following features:
Engine speed governor
Automatic air/fuel ratio control
Torque rise shaping
Injection timing control
System diagnostics
Aftertreatment regeneration control
NOX reduction system controlAdditional Features
The following features provide increased engine fuel economy and serviceability:
Cold starting capability
Tampering detection
DiagnosticsCommon Rail Fuel Injection System
The common rail fuel injection system performs the following functions:
Pump the fuel.
Meter the fuel.
Time the fuel injection.The fuel pump pressurizes the fuel. The fuel pump; pumps the fuel to the common fuel rail. The common rail fuel injectors inject the fuel into the cylinders at a precise time. The fuel is injected into the cylinders with the appropriate volume. Electronic sensors on the engine determine time and volume of fuel injection.Engine Service Life
Engine efficiency and maximum utilization of engine performance depend on the adherence to proper operation and maintenance recommendations. In addition, use recommended fuels, coolants, and lubricants. Use the Operation and Maintenance Manual as a guide for required engine maintenance.Expected engine life is predicted by the average power that is demanded. The average power that is demanded is based on fuel consumption of the engine over a time. Reduced hours of operation at full throttle and/or operating at reduced throttle settings result in a lower average power demand. Reduced hours of operation will increase the length of operating time before an engine overhaul is required. For more information, refer to the Operation and Maintenance Manual, "Overhaul Considerations" topic (Maintenance Section).Aftermarket Products and Caterpillar Engines
In order to maximize fuel system life and prevent premature wear out from abrasive particles in the fuel, a four micron[c] absolute high efficiency fuel filter is required for all Caterpillar common rail fuel systems. Caterpillar High Efficiency Fuel Filters meet these requirements. Consult your Caterpillar dealer for the proper part numbers.
When auxiliary devices, accessories, or consumables made by other manufacturers are used on Caterpillar products, the Caterpillar warranty is not affected simply because of such use.However, failures that result from the installation or use of devices, accessories, or consumables from other manufacturers are NOT Caterpillar defects. Therefore, the defects are NOT covered under the Caterpillar warranty.
